Explanation / Answer

Hi

21. A non-polar bond is form between two identical atoms of equal electronegativity.

22. Se belongs to the oxygen family and S belongs to the same family too. So, S has the closest physical and chemical properties to Se.

23. A p subshell can hold maximum of 6 electrons.

24. Ca has the largest first ionization energy due to its smallest size.
